根據水稻的種植季節，在生產上
，可分為單季稻和雙季稻（連作稻）。雙shuang季ji稻dao中zhong第di一yi季ji種zhong植zhi的de水shui稻dao叫jiao早zao稻dao，第di二er季ji種zhong植zhi的de水shui稻dao叫jiao晚wan稻dao。單dan季ji稻dao
，也ye叫jiao中zhong稻dao
，每mei年nian在zai同tong一yi塊kuai稻dao田tian裏li種zhong植zhi一yi季ji水shui稻dao。北bei方fang地di區qu受shou溫wen度du影ying響xiang一yi年nian隻zhi能neng種zhong植zhi一yi季ji水shui稻dao，即ji單dan季ji稻dao。南nan方fang地di區qu，溫wen度du較jiao高gao，熱re量liang資zi源yuan豐feng富fu，可ke以yi種zhong植zhi一yi季ji，也ye可ke以yi種zhong植zhi二er季ji。根gen據ju地di區qu不bu同tong，單dan季ji稻dao品pin種zhong可ke以yi是shi常chang規gui稻dao和he雜za交jiao稻dao，也ye可ke以yi是shi粳jing稻dao和he秈xian稻dao。連lian作zuo稻dao中zhong，早zao稻dao品pin種zhong感gan溫wen性xing強qiang
，感gan光guang性xing弱ruo，晚wan稻dao品pin種zhong感gan溫wen性xing弱ruo
，感gan光guang性xing強qiang。長chang江jiang中zhong下xia遊you地di區qu的de連lian作zuo稻dao，早zao稻dao為wei秈xian稻dao
，晚wan稻dao有you秈xian稻dao和he粳jing稻dao。華hua南nan地di區qu早zao稻dao和he晚wan稻dao均jun為wei秈xian稻dao。

長chang江jiang下xia遊you地di區qu作zuo晚wan稻dao種zhong植zhi的de粳jing稻dao品pin種zhong如ru作zuo為wei早zao稻dao栽zai培pei，盡jin管guan是shi早zao春chun播bo種zhong，但dan隻zhi有you到dao秋qiu天tian具ju備bei了le短duan日ri照zhao條tiao件jian時shi
，才cai能neng進jin行xing幼you穗sui分fen化hua和he開kai花hua成cheng熟shu

，生sheng育yu期qi明ming顯xian延yan長chang。因yin此ci，晚wan稻dao用yong的de粳jing稻dao品pin種zhong隻zhi能neng作zuo單dan季ji晚wan稻dao或huo連lian作zuo晚wan稻dao種zhong植zhi
，而er不bu能neng作zuo早zao稻dao種zhong植zhi。早zao稻dao品pin種zhong則ze由you於yu感gan光guang性xing弱ruo
，既ji可ke以yi夏xia季ji長chang日ri條tiao件jian下xia抽chou穗sui，也ye可ke在zai秋qiu季ji短duan日ri條tiao件jian下xia抽chou穗sui
，所suo以yi既ji可ke以yi作zuo早zao稻dao種zhong植zhi，也ye可ke作zuo晚wan稻dao種zhong植zhi。翻fan秋qiu種zhong植zhi時shi，生sheng育yu前qian期qi處chu於yu高gao溫wen環huan境jing，生sheng長chang發fa育yu進jin程cheng加jia快kuai
，生sheng育yu期qi縮suo短duan，成cheng熟shu期qi提ti早zao
，產chan量liang降jiang低di。
